myVolts MCH-K303D Adjustable DC Power Supply 30V 3A 110V

Adjustable DC supply 0–30 V

The myVolts MCH-K303D is a switching bench supply that delivers a continuously adjustable 0–30 V output with up to 3 A current. It accepts 110 V or 220 V mains input at 50/60 Hz and is rated for 101–200 W output power. The unit is intended for technicians and hobbyists who need a compact, regulated DC source for circuit testing or mobile phone repair work. It is not suited for applications that require higher voltage, higher current or multiple independent outputs.

Full-featured protection and steady output

Built-in output protection safeguards the load and the supply itself during accidental shorts or overloads. The design maintains continuous operation at full rated load without shutdown, and the regulation keeps voltage stable across the 0–30 V range. These traits mean the supply can stay connected to a device under test for long sessions while delivering consistent, repeatable results.

Compact bench installation

The lightweight chassis sits on a bench without special mounting and connects to mains via a standard IEC lead. A single output terminal pair simplifies wiring, and the front-panel controls adjust voltage and current directly. Users should verify that their mains voltage matches the 110 V or 220 V setting before powering on, as an incorrect selector position can damage the unit.
